PERRIN 22-25 Subaru WRX Front-Pipe w/GESI Cat

Perrin Performance is well-known for making solid upgrades for Subaru vehicles, and this front pipe with a GESI catalytic converter is a prime example. If you're looking to improve your 2022-2025 Subaru WRX's exhaust flow and emissions control, this part is designed to do just that. It replaces the factory front pipe and catalytic converter with a more efficient setup, aiming for better performance without sacrificing emissions compliance where it's permitted.

This front pipe features a high-flow GESI catalytic converter, which is designed to handle increased exhaust flow while still doing its job of cleaning up emissions. The pipe itself is constructed from stainless steel, a strong material that resists corrosion and holds up well to the heat and stress of an exhaust system. Perrin has designed this to be a direct replacement for the stock unit, meaning it should bolt up to your existing exhaust system without needing major modifications, making installation more straightforward. You'll notice an improved exhaust note and potentially a bit more responsiveness from your engine thanks to the reduced restriction.

Keep in mind that this specific catalytic converter is not CARB approved and cannot be shipped to California due to emissions regulations there. Always check your local emissions laws before purchasing and installing aftermarket exhaust components. This front pipe is intended for off-road use or for use in areas where it complies with local emissions standards.
